Answer:

x ≈ 6.6, y ≈ 13.3

Step-by-step explanation:

Using the tangent ratio in the right triangle to find x

tan30° = \frac{opposite}{adjacent} = \frac{BC}{AB} = \frac{x}{11.5} ( multiply both sides by 11.5 )

11.5 × tan30° = x , then

x ≈ 6.6 ( to the nearest tenth )

Using the cosine ratio in the right triangle to find y

cos30° = \frac{adjacent}{hypotenuse} = \frac{AB}{AC} = \frac{11.5}{y} ( multiply both sides by y )

y × cos30° = 11.5 ( divide both sides by cos30° )

y = \frac{11.5}{cos30} ≈ 13.3

irga5000 [103]

Answer:

The future value of this initial investment after the six year period is $2611.6552

Step-by-step explanation:

Consider the provided information.

A student desired to invest $1,540 into an investment at 9% compounded semiannually for 6 years.

Future value of an investment: FV=P(1+r)^n

Where Fv is the future value, p is the present value, r is the rate and n is the number of compounding periods.

9% compounded semiannually for 6 years.

Therefore, the value of r is: r=\frac{0.09}{2}=0.045

Number of periods are: 2 × 6 = 12

Now substitute the respective values in the above formula.

FV=1540(1+0.045)^{12}

FV=1540(1.045)^{12}

FV=1540(1.69588)

FV=2611.6552

Hence, the future value of this initial investment after the six year period is $2611.6552

What is 7+10x-2x-2=-3
Ivahew [28]
7+10x-2x-2=-3

—-Combine like terms...10x-2x=8x and 7-2=5

8x+5=-3
——subtract 5 on both sides.. the 5’s will cancel each other and -3-5=-8

8x=-8
——Divide 8 on both sides...the 8’s will cancel out and -8 divided by 8 = -1

Answer: x = -1
